Best advice is to ditch that tsi fuel system and pick up emanage, AEM F/IC, or PCS XFC. Otherwise take it a tuner and see if they can richen up your map. Do you have a wideband? What are your air/fuel ratios when you say you're lean?

Ya that air fuel gauge is worthless my friend. You really need a wideband to know exactly what is going on with your car. Some good widebands are AEM Uego, PLX, and Innovate.
